Solid Waste

Recommended actions - solve 80% of waste problem
  1. Composting for food waste 
  2. Recycle waste through raddiwalah - paper, glass, wood, rubber, metal ...
  3. Recycle through manufacturer - electronic waste

Root cause of the problem
Non-segregation of waste at source - among food waste and non-food waste
Mixing of waste leads to dumping at land fill sites, stinking etc

Problem areas without solution
Incinerator is a very bad solution
Plastic waste - see plastic to oil solution, may lead to harmful gas emission - not using it seems only option
Bio-medical waste - diapers, sanitary napkin and condom and material with body fluids - blood, sputum etc.
Bio-medical waste - medical waste from hospitals


5 types of solid waste:
  1. Food waste (50 - 60% of total waste)
  2. Paper, Cloth, wood, rubber, plastic, metal - recycle (30% of total waste)
  3. Electronic waste
  4. Construction debris
  5. Bio-medical waste
Hazards due to waste/ process of waste management
     To society in general, rag pickers, municipal workers etc.
  1. Hazard due to bio-medical waste - including baby diapers, sanitary napkin, condom and other body fluid e.g. blood, sputum etc. Medical waste as syringe, stained cotton, glass / plastic bottles of medicines
  2. Broken Glass 
Hazards to public health / environment
  1. Worsening public health due to virus, mosquito problem, toxic soil and water due to waste..elaborate
  2. Contamination of underground water, fresh water lakes, rivers, oceans
  3. Burning of waste leads to harmful gas emissions

Waste Management at household level
-------------------------------------------------------------------------------------------------------------- 
Solution discussion - Composting of food waste
  1. Food waste needs water and air to turn to compost, and 3 months of time
  2. Compost bin should NOT be kept in closed premises - rooms etc, but with at least one side open - balcony etc, the area should be covered out of rain - to keep it at right moisture level
  3. Compost bin should be covered from top to retain right temperature level
  4. Need to churn the waste in compost bin at regular intervals - for air supply to the waste
  5. Initially, to start process of composting - put some old compost - to introduce microorganisms
example by Dailydump.org - 3 clay pots (one over the other) - with small holes and mesh to prevent insects
- trick is right moisture level
        - too wet makes it smelly - should add dry leaves, wood powder etc

        - too dry will not turn into compost - should add water

The compost do not smell if moisture level is right
------------------------------------------------------------------------
Hazardous waste of packaging
--------------------------------------------------------------------
Packaging of chips, chocolates etc are blend of plastic and metal, or paper and aluminum etc - they are not biodegradable, and also not possible to recycle


PIL and manufacturer liability seems to be the only way out
